Figure (top) shows an annualized mean
net upward surface flux
Fs for the ERBE period (February 1985  April 1989) in
W m-2 at T42 spectral truncation. Negative (blue) regions in
equatorial and Tropical oceans represent
a net flux of energy from the atmosphere into the oceans on an annual mean basis.
Other noteworthy features are the significant net fluxes of energy from the
Kuroshio, the Gulf Stream, and the Aghulas Current into the atmosphere.
Ideally, Fs should
be roughly 0 over land areas. Bottom figure
shows the annualized mean net upward surface flux Fs
without land areas masked.
